RULE. If the sum to be divided consist of dollars and cents both, divide as in Simple Division. When a remainder occurs, multiply it by 4, and add the number of fourths that are in the fraction of the sum (if any) to its product : divide this product by the divisor, and its quotient will be fourths; which annex to the quotient of the sum.
When the sum to be divided consists of dollars only, set two cyphers in the place of cents; and then proceed as above directed.
If, when the sum is divided, there are but two figures in the quotient, they are cents; but if there are three or more figures, the two first on the right hand are cents, and all on the left of these are dollars.
Proof: as in Simple Division.

SIMPLE REDUCTION. Reduction is the changing of a sum or quantity, from one denomination to another, without increasing or lessening its value.
Simple reduction is the reducing of sums or quantities which have but a single denomination.
When a sum or quantity is to be changed to a lower denomination than its own, work by
RULE 1.* Multiply the sum or quantity by that number of the lower denomination which makes one of its own.t See notes 1, 2, and 3.
If there are one or more denominations between the denomination of the given sum or quantity, and that to which it is to be changed: first change it to the next lower than its own, and then to the next lower, and so on. See notes 4 and 5.
The reason of this rule is plain : for, if it take twenty shillings to make one pound, it must take five times 20 shillings to make five pounds; and to find how many five times twenty are, we may either multiply 20 by 5, or 5 by 20. Likewise, if it take 4 pecks to make one bushel, it must take 6 times 4 four pecks to make 6 bushels, &c.
+ One denomination is said to be lower than another, when it is of less value ; and higher, when it is of greater value': thus, a shilling is a lower denomination than a pound; and a higher denomination than a penny.
